Success making a joint with hand tools

Sometime ago I tried making joints, however, it was hard and frustrating, as I used a rib saw. This time I tried with a little saw, chisel and many videos about manual tools 😅 The result was a success: I got a good and stable joint, as the two pieces for together. What's now, they are squared! Would you recommend me using a Japanese saw instead the saw from the picture? Thanks a lot in advance
